Agilent ADS is a great tool for circuit simulation on Linux.
1. Install ksh
sudo apt-get install ksh
2. Download and extract ADS2009 installation files. Enter the directory that stores all installation files. Run
./SETUP.SH
and follow on-screen instructions.
Be sure to set the proper path for ADS2009. ADS2009 could be very big, 5.5 GB. So it is better to install it on a separate partition other than your root partition, like below.

Few months ago, I made a video.
Many friends asked me how I made it. Now here it is. This is a very brief one and I will enrich it later.

梦见跑回高中,看到两个高中生在作一个电路,于是看了看
PCB板的一面有一个像手机上那样的方方的液晶屏
另一面是一个我没有见过的元件
那两个高中生演示了一下,把手放到那个我没有见过的元件前面,手来回移动一下于是明白了,那个我没有见过的元件是一个测距的东西,我也不知道是用什么测距的,
超声波还是红外?
更牛的是那个方方的LCD中在显示一个圆,随着距离的改变圆的半径也会变化
而那个板子上还有一个DIP封装的元件,估计是某种单片机吧,猜测是把测距元件传来的信号处理一下,驱动LCD显示那个圆的
